How to tell if you are a Geo-libertarian or a Neolibertarian

This is primer on Geo-libertarianism – Let’s say the whole world consisted of a tiny island. On this island lived a man and a woman. Within 9 months time, this happy couple had a child. Approximately 18 years after that, they decided it was time to teach their teenage punk a lesson in life so they kicked him out of their home. Where is this kid going to go? The parents own all the land. He could pay “rent” to them to live on part of it. But is this fair? Why do the parents get rights to the land simply for getting there first? It was out of the teenager’s control that he was born later then his parents. Do the parents own the land and can they make profit off of it having only lived there first If you say “yes,” you are a neolibertarian. If you say “no,” you are a geolibertarian.
